13.8.5 Popping marks rotates the mark ring like GNU Emacs

The Editor commands
Set Mark with a prefix argument,
Pop and Goto Mark and
Pop Mark and the function
editor:current-mark with the
pop-p
argument now rotate the mark ring instead of discarding the current mark. This makes them compatible with GNU Emacs and allows you to cycle around all of the marks by repeated invocation. The word "pop" in the names is retained for compatibility, even though the operation is now a rotation.
